Electric light



W. E. SIMPSON ELECTRIC LIGHT Filed July 24, 1933 wuc niet WE. @L'WsonPatented Aug., 2Q i935) srl/iras hollow E. Simpson, Princeton,Application fully 24, i933, Serial No. lldl 2 Claires. ('Cl. :Ellis-213)This invention relates to electric lights and more particularly to suchlights w are used for short intervals of time in the manner ci adash-light.

S A primary object of the invention is Ato so construct such a lightthat it may be easily set up in the position in which it is to remainand the light duicirly turned on and off by swinging the bulb carrieroutward and inward and which carrier when the light is not in useprotects the bulb against the weather, if located outside, and againstaccidental breakage no matter where located.

mother object of the invention is to provide a light ci this characterwhich is simple and compact and which may he easily set up at anydesired place ready for use and which may he supplied with current fromeither a self-contained. cattery or from any other suitable source.

in carrying out these objects the invention is susceptible onicdications without departing -ilrom the spirit or sacrificing any othe advantages oi the claimed invention.

En the accompanying drawing Figure l represents e. front elevation oi aportion of a door with this light in place 'for illumimating thelreyhole;

Fig. 2 is a longitudinal section ci the light;

Fig. 3 is a iront elevation of the light with parts broken away and insection; and with the contacts in circuit closing position;

l is a transverse section taken on the line Cl-i ci Il; and

Fig. 5 is a view similar to 2 showing e. slightly different form of theinvention.

In the embodiment illustrated this device is shown placed on a housedoor D in such position that when operated it illuminates the key-holeoi the loclr. it ls particularly useful ou automobiles; on motor boats;as a hed reading light; in closets; on stairways; cellars; and in anyother place where a light may be useful, and it may he mounted in anysuitable or desired manner.

As illustrated in Figs. l to l an open-front casing l is shown having atopy 2, baci: il, sides l l and an upper front ledge the latter beingpreferably equipped with an overhanging lip to shed water and preventits entrance into the casing. All of these parts may be of metal orother suitable material and they :may he formed integrally as a singleunit or of pieces mechanically united.

Secured to the inner :lace of the bacir 3 near its upper end is a platel having at its lower end an inwardly and upwardly ex. ending ioot i3 tohe located in the path of a swlngably mounted bulb carrier il). Thisfoot il cooperates with. a small dry cell battery l) carried oy the'oulh carrier ill and hy means of which the battery terminais Q' and 9are forced into contact with and respectively engage the bulb terminali5 and the metal hulls support ifi in which the bulb shank or neck isscrewed. rThis occurs when the carrier iii is swung outward as shown indotted lines in Fig. 2 thereby closing the circuit and lighting the bulbiii. When the carrier l@ is swung inward into the full line position ofFig. 2 the battery is moved away from foot i3 and its terminal il"disengaged. from the bulb support ld thereby breaking the circuit andextinguishing the light.

The bulb carrier is shown in the iorrn of a pocket-like casing pivotallymounted in the open-iront casing to swing into and out o said casingthru its open iront and when in normal closed position ionns a closurefor said 'iront opening. This carrier pocket it includes a iront il andhach the iront extending at both ends beyond 'the ends of the back asshown clearly in Fig. 2. Sides lll connect the iront and haci: and areci a width slightly narrower than the sides of casing l so that when thecarrier l@ is swung inward into closed position the iront i l lies flush`with or slightly below the iront edges oi sai sides i of casing i withthe upper end of iront il underlying; and abutting the inner face ofcasing l. rihe sides lll which connect the iront il with haci; i?. ofthe pocketdllre carrier l@ have their ends bevelled as shown in Fig. 2and the lower end of back lil carries an inwardly extending shelf ifiwhich is provided with a bulb socket il] so that when a bullo is screwedtherein the depending lower end ci front li projects heyond the bulb andforms a protective hood there ier. The upper end of baci; i2 carries a'transversely extending tubular barrel or hearing i3 to receive a pintleiii which is shown in the form of a holt extending thru the sides i oi'casing l and thru said barrel forming a plntle i or pivotal ly mountingcarrier casing i@ in casing l. lnnut El) on said holt when sufficientlytightened rictionally holds carrier lil in any of its positions: When somounted casing i@ has its upper end located in casing i and extends farenough thereinto to abut the inner face of ledge when casing i il isclosed as shown in full lines in 2.

lt will thus be seen that when a dry cell il is placed in the pocket oi'casing lil one ci the terrninals 9' of said cell will lightly rest onthe terminal or contact lll of bulb iii and the other end of 'thebattery will be so located as to engage foot 8 when the casing W isswung outward into the dotted line position of Fig. 2. When suchengagement occurs the battery will be forced into the pocket by thepressure exerted by said foot and cause the other terminal 8" of battery9 to also engage the bulb support or shelf I with which the shank of thebulb is in electrical contact thereby closing the circuit and lightingthe bulb. The light will remain on as long as the casing i isswungoutward and when manually pushed inward to closed position thecontacts will assume the full line position shown in Fig. 2 therebybreaking the circuit and extinguishing the light.

A mounting or attaching element in the form of a bracket 2l is carriedby the casing li being fastened' in any suitable lmanner preferably tothe casing back 3 for mounting the light on a suitable support in anydesired locality. This bracket may be of any desired shape according tothe'place where the light is to be used and it may be equipped with anysuitable means for securing it in place, screw holes being here shownfor this purpose.

In Fig. 5 the light is shown connected with a current supply wire 22designed to be connected with any suitable source of electricity, thedry cell 9 of the other figures being omitted in this form.

The current supply wire 22 is connected with the plate 'I' by aninsulated bolt 23, said plate forming one pole of the circuit and thefoot 3' thereof projects in the path of a cooperating contact 24 carriedby the bulb carrier or shield I0' which is similar to that shown in theother gures. This contact 24 is shown in the form of a metal plate orstrip secured to casing i0' and having at its lower end a laterallyextending ringer 25 engaged with the'bulb contact or terminal 26, saidbulb casing or base shell being grounded on casing l0'. The upper end ofstrip 24 is bent inward to form a nger 2T to be engaged by toot t' whencasing l0 is swung outward a predetermined distance and thereby closethe circuit and light bulb i5. l

It is obvious that in the form shown in Figs. i to 4 when the bulbcarrier or shield i0 is swung outward a certain distance the foot 8 willengage the battery cell 9 and check its movement so that the furtherswinging out of the shield will cause the battery to be movedlongitudinally relatively to the shield and thus cause the springcontact 9, which is shorter than contact 8', to

engage the bulb casing or base shell i6 and thus complete the circuitand illumine the bulb.

When the shield is swung inwardly the battery is'moved away from foot 8releasing the battery from pressure, and the force of spring contact '9'will move the battery rearward relatively to the 'shield and separatecontacts 9" and i6', break the circuit and extinguish the light.

In the form shown in Fig. 5 When'shield I0' is swungV outward contactnger 21 engages foot 8' vlocated in its path and closes the bulb circuitand 'limited by engagement of the toe of foot 8 with the front wall ofshield I0 or by the battery 5 engaging member I.

l claim as my invention: Y 1. In an electric light, the combination of abase member, a bulb shield movably connected to the base member andhaving an electric light bulb and a storage battery cell, sa'id bulb andcell having cooperating contacts, an element on the base member inthepath of the cell when the shield is moved in one direction whereby themovement of the cell is checked and the electric circuit is completed byfurther movement of the bulb into engagement with the contacts oi. thebattery cell.
